OIL-BURNER.

SEECIFIGATION forming part of Letters Patent No. 499,088, dated June 6, 1893.

Application filed July 30, 1892. Serial No. 441,669. (NqmodeL) Be it known that I, JACOB BARROW, a citizen of the United States of America, residing at \Vindfall, in the county of Tipton and State of Indiana, have invented certain new and useful Improvements in Oil-Burners and I do hereby declare the followingto be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in oil burners.

The object of the invention is to provide an improved means for burning oil for cooking and heating purposes; and it consists in the construction and combination of the parts, as will be hereinafter fully set forth and par-. ticularly pointed out in the claims.

In the accompanying drawings forming part of this specification: Figure 1 is a view showing my invention applied to a cooking stove. Fig. 2 is a side elevation of the burner. Fig. 3 is a plan view, one-half of the burner being removed. Fig. 4. is a transverse section through the line a7ac of Fig. 3.

A designates the base of the burner, which when in use may be placed upon the ordinary grate bars of a heating or cooking stove. This base is preferably of cast iron and is provided at one end with an air mixer, B, into which the vaporized oil is injected and mixed with atmospheric air by the discharge nozzle 1) of the oil pipe 0, which oil pipe is provided with a bend so that it will lie over and above the base A. The base is provided with troughs a a located on each side, and with an end trough a at a little higher elevation than the side troughs. In the side troughs are placed non-combustible absorbent strips 0 0, preferably of asbestos or a composition thereof. The inner walls of the troughs a a. are

extended upward to provide the walls 01 cl, which incline upward from the end adjacent to the air mixer, and the upper edges of the same are provided with notches or apertures cl for the purpose to be hereinafter set forth. Within the inclined walls is an arched wall D, around which is a trough; and the end of this arched wall adjacent to the mixer B is a little lower than the opposite end, and is also tapered as shown.

E designates a covering plate, which is adapted to rest upon the upper edges of the walls 61 so as to inclose the arched wall D and trough surrounding the same, and this covering plate is provided with a central row of perforations, e and intermediate perforations 6' through which the gases pass.

It will be observed from the construction hereinbefore described that the burner is reversible and may be placed in a stove from either side. In placing the burner in the stove it is preferable to place it so that the lower row of holes or apertures 01' will be on a level; this will give the troughs on each side of the burner suflicient fall to allow the oil to run the entire length of the same When let in to start the fire. The pipe 0 in which the vapor is generated will rest upon the support or flanges at the side and end of the burner, said pipe and the mixer B of the burner being partially outside of the door of the stove. The oil pipe G, which connects with an oil reservoir is coupled to one end of the pipe 0 bya casting comprising a suitable regulating valve having a movable spindle, and the nozzle 1) at the end of the pipe 0 may have aturning plug as shown in Fig. 1, if desired.

In starting the fire the valve h is opened to allow sufficient oil to spray into the burner and thoroughly saturate the asbestus strips in the troughs on each side of the burner, which oil is then lighted, which will give out enough heat to generate vapor in the pipe 0; the vapor flowing through the connection b, which is provided with a very small aperture will mix with the air and flow through the perforations e and e and be ignited to be used for heating or cooking purposes. This device will generate the oil into vapor, obtaining and utilizing to the fullest extent all the heat giving qualities thereof, and by mixing the vapor thoroughly with cold air before entering the burner will provide complete com bustion and give greater heat and be free from smoke, soot and smell. The pressure of the oil in the pipe G is sufficient to overcome any back pressure.

ICO

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. An oil burner consisting of a basehaving longitudinal side troughs and vertical walls which are inclined longitudinally and provided with apertures d, the base having within the vertical walls a raised portion D and beyond the same an air passage, as B, an arched cover adapted to rest upon the vertical walls to form a chamber above the raised portion D, said cover being perforated, and an oil supply pipe bent to lie over the side troughs, one end of said supply pipe leading into the air passage of the base,substantially as shown, and for the purpose set forth.

2. In an oil burner, the combination with the base A having at one end an air passage,

said base having upwardly projecting walls d which incline longitudinally, a raised portion D within said walls which provides with the perforated cover a chamber of diminish- 7 ing size from end to end, a perforated cover resting upon the inclined walls, and a supply pipe which is adapted to encircle the perforated cover, said pipe having at one end an apertured connection which leads into the air passage formed in the base, substantially as shown and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
